Selective extraction of cobalt ions through polymer inclusion membrane containing Aliquat 336 as a carrier

Osman TUTKUN

This study reports the selective separation of Co (II) from mixtures of cobalt and nickel solutions using cellulose tri-acetate (CTA)-based polymer inclusion membranes, which incorporated the commercial extractant trioctylmethylammonium chloride (Aliquat 336). Tributylphosphate (TBP) was used as a modifier, and 2- nitro phenyl pentyl ether (2-NPPE) was applied as the plasticiser to prepare the membranes. Several important transport parameters such as the plasticiser concentration, carrier type, carrier concentration, pH of acid, stirring speed, stripping solution type and concentration, comple ...Более

Characterization of polymer inclusion membrane containing Aliquat 336 as a carrier

Osman TUTKUN

The presented research is about characterization of Cellulose Triacetate (CTA) based Polymer Inclusion Membranes (PIMs) which incorporated the commercial extractant Aliquat 336, Tributylphosphate (TBP) as modifier and 2-Nitro Phenyl Pentyl Ether (NPPE) as plasticizer, for the preparation of the membranes. Chemical and physical characteristics of the synthesized membranes especially membrane thickness and side difference effects were investigated. Different surface structures and membrane thickness affect the extraction efficiency of membranes. Membrane extraction experiments were studied where ...Более

Determination of Moisture Transport Parameters of Some Fruits Under Open Sun Drying Conditions

İnci Türk TOĞRUL | Hasan TOĞRUL

In order to determine the behavior of fruits during drying under natural conditions, open sun drying experiments were conducted on apricots, grapes, peaches, figs, and plums. The drying rate curves of these fruit did not contain constant rate period, but showed a falling rate period. In the present work, Biot numbers and the mass transfer characteristics—namely moisture diffusivity and moisture transfer coefficient—of selected fruits were evaluated by drying coefficients (S) and lag factors (G). The experimental results exhibited mass transfer Biot numbers in the range of 0.115–0.158, thus ind ...Более

Selective separation of gallium from various ions by polymer inclusion membranes based on CTA/PVC blend using TOPO as carrier

Osman TUTKUN | Kurmancan KAPAROVA

Selective transport of gallium from HCl media containing other ions such as Zn, Co, and Ni, by polymer inclusion membranes (PIM), based on CTA/PVC blend using trioctylphosphine oxide (TOPO) as carrier and 2-nitrophenylpentyl ether (2-NPPE) as plasticizer is studied. The effect of various parameters such as the HCl concenration in the feed, HCl concenration in the stripping phase, carrier (TOPO) concentration, 2-NPPE concentration, the cellulose triacetate (CTA)/poly(vinyl chloride) (PVC) as the polymer-blend was experimentally studied and the optimum conditions were determined. It was possible ...Более

The investigation of the chemical and technological properties of biomass waste from plant raw materials = Исследование химико-технологических свойств отходов биомассы растительного сырья

Külümkan SARTOVA

Целью данной работы является изучение технического, химического и группового состава биомассы хлопчатника (лат. Gossypium) и полыни – эстрагона (лат. Artemisia Dracunculus L.) для установления их пригодности при получении химических продуктов. Результаты исследования позволили установить, что биомасса хлопчатника и полыни – эстрагона может быть использована в качестве сырья для получения химических продуктов и адсорбентов. Исследование химического состава анализируемых растений показало, что их можно использовать в дальнейшем для получения целлюлозы (37 до 48%), лигнина (21–31%), гемицеллюлоз ...Более

Synthesis of Smart Food Packaging from Poly (Gelatin-co-Dimethyl Acrylamide). Citric Acid-Red Apple peel Extract

Nahit AKTAŞ

A novel and smart hydrogel was synthesized from N, N dimethyl acrylamide (DMAAm), gelatin, and citric acid (CA) red apple peel extract (RApE) to be utilized as a multi-functional food packaging material. The p(Gelatin-co-DMAAm)/CA-RApE was prepared through a redox polymerization technique in film form in petri dishes. Mechanical and water resistance of the p(Gelatin-co-DMAAm)/CA-RApE was improved by the addition of citric acid and N, N, methylenebisacrylamide (MBA) as cross linker. The characterization of p(Gelatin-co-DMAAm)/CA-RApE was carried out by Fourier transform infrared spectroscopy (F ...Более
